shush was written to be a generic wrapper around cron jobs so that it can be applied to any command without having to modify it or create a custom wrapper for it. In a sense, it solves a fairly simple problem, but it also brings some powerful features making it a useful tool beyond cron jobs.
- Multiple reports (for the output) may be defined
- Decision to send a report (or not) is configurable based on:
- Output content analysis (using regular expressions)
- Command exit code
- Size of output
- Command execution duration
- Support for plain text, enriched text and HTML report formatting. (The latter two allow rendering part of the output in bold.)
- Various timeout actions such as notification and command termination
- Locking support
- Progress report logging via syslog
- Automatic crontab file updating based on shush's configuration
